Weather strip



Patentecl Jan. 21, 1939 UNITE STATES PATENT OFFICE WEATIIER STRIP Applicaton fi1ed. Mareh 28, 1928. Sieral No. 265,252.

This invention relates t improvements in weatherstrips, and more especially to weatherstrips adapted for use with hinged closures such as French or casement windows, doors,

hinged skylights, and the like.

A11 object of the invention is to provide an improved weatherstrip adapted to form a nove1 and simple weatherproof oint between a closure and the associated casement when the closure is swung to c1osing position.

A further object is to provide a weatherstrip especially adaptable for use on the top portion of the casen1ent to provide a sea1 between it and the top of the associatec1 closure.

A further object of the invention is to provide an improved weatherstrip which is of especial simple construction, and which may easi1y and quickly be constructed anc1 applied, and which is capab1e of eficiently performing the service required of it.

With the iforegoing and other objects in view which will be made manifest in the following detailed description anti specifically pointed out in the appended claims, reference is had to the accompanying drawings for an illustrative embodiment of the invention wherein:

F igure 1 is a cross sectional view of a portion oi? a casement wino1ow and the top of the 39 casement therefor, and the weatherstrip in sealing position therebetween.

Fig. 2 is a view similar to Fig. 1, with the window moved from c1osed position.

Fig. 3 is a perspective view of the window and casing showing the weatherstrip as viewed from the outside of the window.

Fig. 41 is an enlarged, fragmentary view showing the weatherstrip in sea1ing position.

Fig. 5 is an enlarged, diagrammatic view showing the weatherstrip in sea1ing position, and indicating in dotted lines the position of the weatherstrip when released.

Fig. 6 is a perspective view of a port-ion of the weatherstrip.

In terms of broad inclusion, the weatherstrip of the present invention comprises a strip of resilient material adapted to be secured a1ong 011e edge to the casing of a swinging closure. The body of the strip is bent fron1 adjacent the attached edge toward the closure in the direction of opening of said closure, to be engaged thereby, preferably by the outer corner of the closure when in c1osed position. Tlie unattached edge of the strip is cur1ed back upon itself to provide an inclined portion against which the elosing closure may impinge to spring the weatherstrip sufliciently to allow the closure to close. The curled portion also acts as a gutter to lead water away from the top of the closure in the event that the Weatherstrip is applied to the top of the casement.

In greater detail, the preferred embodiment of the weatherstrip of the present inventi0n is shown applied to the top rail 6 of a window casement 7 within which the casement window 8 is hingedly mounted.

The strip which is indicated in its entirety at 9, is preferably formec1 of suitab1e resilient,

non-corrosive material such as strip brass 01 bronze. Any means for attaching the strip to the casement may be employed. In its preferred form, the strip is composed of such light material that a plurality of nai1s 13 may be driven through the strip into the casement 7 to seourely hold the strip in operative positien.

The body portion 16 of the strip 9 is deflected downwards from the attached edge 11 toward the window 8 in the direction of opening thereof. The strip 9 is of such width that when the window 8 is in closed position, it extends a short distance beyond and be1ow the upper outer corner 17 of the window 8, as c1early shown in Figs. 1 and 4. Beyond the point 18 which is beyond a11d be1ow the corner 17 the unattacheci edge is curled backwards to provide a gntter 19 extending across the top of the window 8.

It is to be understood that the natural resiliency of the meta1 of which the strip is composed, is snch that when the winc1ow 8 is open, the point 18 on the strip 9 will be below the top surface 21 of the winclow 8 as shown in Fig. 2 and as indieated in dotted 1ines in tion. Consequently, when the window is fully closed, the resiliency of the metal will canse the strip 9 to press tightly against the upper outer corner 17 of the window t0 pro- \'1de en eect-ive seal against the passage of wind or water between the top rail 6 of the casing and the window 8.

The p0int 18 of the strip, as pointed out prtwiously Will be positioned slightly below the top of the window 8, s0 as te preclude the possibility of water flowing under the strip 9 0nto the top surface 21 of the window 8 by capillary attraction.

The gutter 19 serves to entrap any water which might be flowing down the sides of the structure in which the casing 7 is mounted, above the window 8, and 1ead such water to the sides of the window to discharge it.

It may be readily understood that I have thus provided an improved type of weatherstrip which is not only capable of operating very efliciently to provide a sea1 between the edges of a window and the associated casing, but which is also very simple and durable in structure, which is very inexpensive to manufacture, and which may be easily and quickly installed.

Various changes in the details of construetion may be made without departing from the spirit and scope of the invention as defined by the appended claims.

I claim:

1. A weatherstrip for establishing a seal between a hingedly mounted closure and its casing, and comprising a resilient strip secured along one edge to said casing, said strip being deflected frorn adjacent its attached edge toward the closure in the direction of the opening of said closure to be engaged thereby and to extend beyond the corner thereof when elosed.

2. A weatherstrip for establishing a sea1 between a hingedly mounted closure and its casing, and comprising a resilient strip secured along one edge to the top of said easing, said strip being deflected downwards fro1n its attached edge in the direction of opening of the closure to be engaged by the outer corner thereof when closed.

3. A weatherstrip f0r establishing a seal between a hingedly mounted cIosure and its casing, and comprising a resilient strip secured along 0ne edge to the top of said casing, said strip being deflected downwards frorn its attached edge in the direetion of opening of the closure to be engaged thereby and to extend beyond and below the outer corner thereof when closed.

4. A weatherstrip for establishing a seal between a hingedly mounted closure and its casing, and comprising a resilient strip secured along one edge to the top of said casing, said strip being deflected downwards from its attached edge in the direction of opening of the closure to be engaged thereby and to extend beyond and below the outer corner thereof when closed, and the unattaehed edge of the strip being cur1ed upwards to provide L gutter.

5. A weatherstrip comprising a resilient strip bent to provide a fastening edge extending longitudinally thereof and a body portion inc1ined downward from said fastening edge, the 0uter edge of said body portion being cur1ed upward to provide a gutter.

In test-imony whereo I have signed my name to this s ecification.
